Synthesis and biological evaluation of sulfonylcyanoguanidines and sulfonamidonitroethylenes as bioisosteres of hypoglycemic sulfonylureas
摘要:
Sulfonylcyanoguanidines and sulfonamidonitroethylenes are bioisosteres of hypoglycemic sulfonylureas and were prepared and evaluated for their insulin release potency from rat pancreatic islets. At 25 mu M, both bioisosteres of glibenclamide, sulfonylcyanoguanidine 22 and sulfonamidonitroethylene 23, were as potent as their parent on insulin secretion.

In this study, the synthesis of 15 new glibenclamide analogues is described. The conformational trends of these analogues were investigated using Monte Carlo conformational analysis. The conformational analysis results resolved the discrepancy between previous molecular modelling simulations of glibenclamide and allowed rationalizing the effect of aqueous environment on the overall conformation. The
